PILE-POINT.

SPECIFICATION forming part of Letters Patent No. 748,705, dated January5, 1904.

Application filed July 9, 1903. Serial No. 164.844. (1% model.)

inclosure or like structure considerable difficulty is experienced inalining the piles and causing their subjacent longitudinal edges to abutto provide a close joint.

This invention has for its object to overcome the aformentionedobjectionable features and to insure the ready penetration of the pileinto the bed of the stream or other formation when applying drivingforce thereto. 7

The invention consists, essentially, of a metallic point for readypenetration of the soil, said point being transversely inclined toinsure lateral movement of the pile simultaneously with its advance,whereby a tight joint between adjacent piles is obtained. Ears projectfrom one end of the point to embrace the edge portion of the adjacentpile to compel alinement of the piles without necessitating lateralprying or bracing, which is expensive and the source of no end oftrouble.

For a full description of the invention and the merits thereof and alsoto acquirea knowledge of the details of construction of the means forefiecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a perspective view of a section of board piling embodying theinvention. Fig. 2 is a side view of the lower or driving end of a pile.Fig. 3 is a vertical section'on the line X X of Fig. 2. V Fig. Lisaperspective view of the pile point, the dotted lines indicating thelower end portion of the pile. Fig. 5 is a perspective view of thepile-point as seen from the remote end of Fig. 4.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

' The pile-point is of metal and may be cast or fashioned from platemetal or otherwise constructed as found most advantageous. The point isoblong, the length depending upon the Width of the pile for which thepoint is designed. The lower or penetrating end 1 of the point has itssides oppositely inclined and intersecting in an edge, which cleaves thesoil as the pile is driven. Flanges2 project upwardfrom the penetratingend 1 and are spaced apart a distance corresponding, approximately, tothe thickness of the pile, so as to receive the lower end thereof, asindicated mostclearly in Fig. 3. The flanges 2 project at one end ashort distance beyond the penetrating end 1, as shown at 3, to formguide extensions, which embrace opposite sides of the edge portion ofthe pile adjacent to the one being driven. This is shown most clearly inFig. 1. The opposite end of the flanges 2 are set in from the proximalend of the part 1 a distance corresponding to the projection of theextensions 3, so as to receive the latter when the piles are driven,

with their lower ends about in line, as indicated most clearly inFig. 1. The cleaving portion of the point is inclined in the directionof the width of a pile upwardly and away from the pile previouslydriven,whereby the tendency of the point is to move the pile beingdriven toward the pile previously driven, thereby insuring a close jointbetween the piles, as will be readily comprehended. The pile beingdriven has the guide extensions 3 of its point embracing opposite sidesof the last pile previously driven and which formsa guide for the pilebeing driven.

. The lower end of the pile is fitted between the flanges 2 and squarelyupon the upper edge of the penetrating end and is secured to the pointby fastenings passed through openings in the flanges 2 and through thelower end portion of the pile, as will be readily understood.

Having thus described the invention, what is claimed as new is- 1. Apile-point provided with guide extensions at one end for embracingopposite sides of the pile previously placed in position so as to insurealining of the pile being driven, substantially as set forth.

2. A pile-point having spaced flanges for securance of the same to thelower end of a pile and having said flanges projected at one end to formguide extensions, substantially as described.

3. A pile-point comprising a penetrating end and spaced flanges set infrom one extremity of the penetrating end and projecting from theopposite extremity to said penetrating end to form guide extensions,substantially as specified.

4. The herein-described pile-point of ob-
